About this tool

CSS Flexbox is a one-dimensional layout model that provides powerful alignment and distribution capabilities. Our Flexbox Playground lets you experiment with every Flexbox property in real-time: flex-direction (row, row-reverse, column, column-reverse), justify-content (6 options for main-axis alignment), align-items (5 options for cross-axis alignment), flex-wrap (nowrap, wrap, wrap-reverse), and gap. Adjust the number of child items and see how they respond to different property combinations. The tool generates clean CSS code that you can copy directly into your project. Use it to learn Flexbox, prototype layouts, or quickly generate the exact CSS you need for navigation bars, card grids, centering, and responsive layouts.
